Honey Bee
Pollinator
Honey bees are extremely important pollinators.
They fly from plant to plant gathering nectar,
spreading pollen while they do it. Many fruit and
vegetable farmers rent bee colonies to pollinate
their crops. Studies have shown that the work that
honey bees do leads to billions of dollars of crop
production.

insect because it eats pests, like aphids,
that eat crops.

Eastern Hercules
Beetle
Decomposer
Eastern Hercules Beetles are native to North America; they
live in forests because the beetle larvae feed on decaying
wood. The beetles help to turn the wood back into soil so
that new trees can grow. This keeps the forest healthy.
